New York Yankees vs. Cleveland Guardians

Market context

The Yankees travel to Cleveland for a regular-season matchup on 10 June, with the game scheduled for 1:10 PM ET. The 98% implied probability reflects the Yankees' stronger historical record against the Guardians and their generally superior regular-season performance. However, this probability sits notably higher on Polymarket than comparable decimal odds on Betfair or Kalshi, where the same matchup typically reflects 1.02–1.04 odds for a Yankees win—translating to roughly 96–98% implied probability depending on the book's overround. The discrepancy often stems from differing fee structures: Polymarket's 2% maker and taker fees versus Kalshi's tiered commission model can shift how traders price edge, particularly in heavily skewed markets where liquidity concentrates on one side.

Recent form and injury status will shape whether this probability holds. The Yankees' roster depth and pitching rotation depth typically favour them in June matchups, though Cleveland's bullpen has proven competitive in recent seasons. Traders should monitor lineup announcements 24 hours before first pitch, as unexpected absences or roster moves can shift the calculus. The settlement window extends to 17 June, allowing for postponements due to weather—a material consideration for early-season outdoor baseball in the Midwest. Kalshi's explicit tie-resolution protocol (50-50 split) differs from some offshore books, which may void such bets entirely, creating a subtle but meaningful distinction for risk management across platforms.

Methodology

This page compares New York Yankees vs. Cleveland Guardians specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to Kalshi Alternative UK, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
